SPECIFICATION forming part of Letters Patent No. 786,936, dated April11, 1905.

' Application filed June 2, 1904. Serial No. 210,850.

To all whom, it may concern:

Be it known that I, REIsoN C. WRIGHT, a citizen of the United States,residing at Colorado Springs, in the county of El Paso and State ofColorado, have invented a new and useful Sash-Fastener, of which thefollowing is a specification.

This invention relates to sash-locks such as are designed to lock a pairof window-sashes toeach other and to lock one of them to thewindow-frame.

The prime object of the invention is to improve the construction of suchdevices by rendering them capable of being locked by a simplelongitudinal movement of one locking member instead of by the compoundmovements which are necessary upon most prior devices of the characterindicated.

Further objects of the invention are to' simplify and strengthen theconstruction of such devices.

With these objects in View the invention resides `in the combination andarrangement of parts and in the details of'construction hereinafterdescribed and claimed.

In the accompanying drawings, forming part of this specification, Figure1 is a perspective view showing the sash-fastener applied to awindow-sash, and Fig.y2 is a perspective view ofthe device removed.

The reference-numeral 1 indicates part of the window-frame, 2 thelower-sash, and 3 the upper sash. A series of sockets 4 is formed in thewindow-frame 1, a similar series 5 being formed in the upper sash 3. Thesockets 5 in the upper sash are preferably formed near to the glassalong the inside of the sash.

Fastened in any suitable manner to the lower sash 2 is the base-plate 6of the improved locking device. .Iournaled in lugs 7 and 8 upon theplate 6 is a locking member 9, having a crank portion 10. One end of thelocking member 9 is provided with a bent portion 11, which is adaptedwhen the member is partially rotated to engage one of the sockets 5 A inthe upper sash 3. The member 9 is capable of longitudinal movement inits bearings for a purpose presently to be described. Movablelongitudinally in lugslQ and 13 on the base-plate is a locking member14, having a handle portion 15. The member 14, which is preferably at anangle to the member 9, is formed with a loop 16, that iits over thecrank portion 10 ofthe member 9. The end of the member 14 opposite tothe handle portion 15 is adapted 'to fit into one of the sockets 4 intheV window-frame. A pair of uprights 17 may be placed upon thebase-plate 6 on oppo- 'similar upright 18 may be located adjacent to themember 14, as shown.

Constructed as above described, the operation of the improved lockingdevice is'as follows: By moving the locking member 14 forward to engageone of the sockets 4 the locking member 9 is caused simultaneously toengage lone of the sockets 5. Then by turning the locking member 14 uponits axis until the loop 16 fits over the upright 18 rearwardlongitudinal movement of the member 14 is prevented and both lockingmembers are held` in locked position. The two members are unlocked byturning thev member 14 and retracting it longitudinally. It will beobserved that the uprights 17 limit the rearwardturning movement of thelocking member 9, thus l retaining said member always in operativeposition, and that when the locking member 14 is retracted the uprights17 are upon opposite sides of the loop portion thereof, thus` preventingit from turning, and so holding it always in operative engagement withthe member 9. From the foregoing explanation it will be apparent thatthe two locking members are operated by a longitudinal movement of onemember. If it be desired to use merely the locking member 14, thelocking member 9 may be moved longitudinally in its bearings until itscrank portion leaves the loop of the member 14, after which it ispossible to operate the member 14 without affecting the member 9.

In manufacturing the device the locking menbers 9 and 14 may be made ofwire, if desire The sash-lock of this invention is simple, durable,strong, and inexpensive in construction, as well as efficient inoperation. In its IOO and in its details of construction it presents animprovement over prior devices of a similar character.

Changes in the precise embodiment of the invention illustrated anddescribed may be.

. made within the scope of the following claims Without departing fromthe spirit of the invention.

Having thus described the invention, what is claimed isl. A sash-lockincluding a pair of members one of which has oscillatory movement to andfrom locking position and the other longitudinal movement to and fromlocking position, said members having interengaging loop portions,whereby locking movement of the longitudinally-movable member will betransferredto the oscillatory member.

2. The combination in a sash-fastener, of a pair of locking members, oneof which has oscillatory movement to and from locking position, and thesecond member being movable longitudinally to and from locking position,interengaging loops formed on both members,

and means engaging one of said members lor holding both in lockedposition.

3. A sash-lock comprising a longitudinallymovable locking member, arotary locking member connected therewith and operated thereby, andmeans for holding said members against movement by turning thelongitudinally-movable member.

4. A sash-lock comprising a longitudinallymovable locking memberprovided with a loop and a rotary locking member provided with a 3 5crank, said loop being adapted to engage said crank when both membersare in retracted position, and means to engage said loop when saidmembers are in operative position, said loop and crank being out oi'engaging contact 40 with each other when in such latter position.

In testimony that I claim the foregoing as my own I have hereto aitlxedmy signature in the presence oi' two witnesses.
